Hi all,
I'm studying the message in GSM system . But i cannot find out what messages exchange when a subscriber back to GSM network or he turns the cell phone on. So please help me to answer the question;
- On IN network of GSM, what is the message exchange (TCAP, camel) while subscriber back to GSM network or he turns the cell phone on
- Is there any difference between TCAP exchange when subscriber back to GSM network or he turns the cell phone on?

Thanks and regards,

TCAP

Hi sangamesh,
when PAGCH is sent to register a cell channel on power on, gsm map location update function is used, is there any message exchange between SCP of Intelligent network (like TCAP, CAmel...) ? so that we could capture and find this kind of message by wireshark. We only can access SCP of the network but don't know which message should be found
